WELL FISHING-TOOL.

SPECIFICATION forming part of Letters Patent No. 784,055, dated March 7,1905.

Application filed March 18, 1904. Serial No. 198,776.

part of this specification, Figure 1 is a side elevation of my improveddevice. Fig. 2 is a similar v1ew,'partly broken away, showing the partsin grasping position. Fig. 3 1s a bottom view of the same, and Fig. 4 isa detailed view of a part of the device. I

In the drawings, A represents a sleeve carrying a series of spring-armsSlidable within the sleeve is a rod 4, supporting at its lower end acollar 5,which incloses the springarms. The collar 5 is connected withthe rod 4: by arms 12, the collar and arms 12 constituting a cage topass around the object to be extracted, as hereinafter set forth. Therod 4: is adapted to be connected at its upper end by means of a coupler6 to the ordinary pumprod or other suitable rod 7. The sleeve A isconnected, as by a coupler 8, with a pipe 9, which may be thewater-pipe. A washer 11 is interposed between the sleeve A and pipe 9,against which washer the coupler 6 abuts to limit the movement of thecollar 5.

In use the device is lowered into the well with the spring-arms closed,as shown in Fig. 2. WVhen lowered to the bottom of the well, the rod 7will be raised to release the springarms 3 and allow their toothed ends10 to pass around the object which it is desired to eX- tract. Byforcing the rod 7 downward, as shown in Fig. 2, the collar 5 is carrieddown upon the spring-arms to hold the ends of the spring-arms inclamping position against the object, when the same can be drawn fromthe well. The arms 12 of the collar 5 forma space into which the objectmay extend, and thus permit a firm grip upon the object to be secured.The sleeve A and pipe 9 serve as a guide for the rods 4- and 7,preventing bending of said rods.

The device, as it will be seen, is simple and can be easily operated,and by it broken tools &c., can be extracted from the bottom of drilledwells which cannot be successfully extracted by the ordinary wellfishingtools.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A device of the class described compris ing a sleeve, a series ofspring-arms carried by said sleeve, a rod slidable in said sleeve, aseries of outwardly-branching arms extending from the lower end of saidrod, and a collar supported from the lower end of said branching armsand inclosing said spring arms, for the purpose set forth.

2. A device of the class described comprising a sleeve, a series ofspring-arms carried by said sleeve, a rod slidable in said sleeve, andan open-end cage supported by, and eX tending beyond, the lower end ofsaid rod, the open end of said cage surrounding said spring-arms wherebyan object grasped by said spring-arms may extend into said cage.

3. A device of the class described, comprising a pump-rod and aninclosing pipe, a sleeve detachably connected with the lower end of saidpipe, a series of downwardly-extending spring-arms carried by saidsleeve, a rod detachably connected with the lower end of the pump-rod,and a collar supported by said lower rod and inclosing said spring-arms.

4. A device of the class described, comprising, in combination, apump-rod and inclosing pipe, a sleeve connected with the lower end ofsaid pipe, a series of downwardly-extending spring-arms carried by saidsleeve, a slidable collar inclosing said spring-arms, a rod connectedwith said collar, a coupling connecting said collar and rod with saidpumprod, and a washer interposed between said pipe and sleeve andserving as a stop for said couplin In testimony whereof I aflix mysignaturein presence of two witnesses.
